Hey wait! You have choices!

No, it's not red - it's green

Okay, just about everyone has a red laser pointer. But, we're pretty sure you want to be a superior geek - and doing it with a green laser is the way to go.

This pointer is significantly brighter (about 50 times) than a
red laser pointer and because of its unusual color it is much more
noticeable. I mean come on, a 532 nm green laser wavelength is
obviously superior to a laughable 650 nm red laser wavelength. And
unlike a red laser, the green beam itself can be seen in mid-air in
dark conditions, not just the laser beam dot. This allows the green
laser pointer to be used for pointing to star constellations
(skypointing) and also just generally look cool as hell. The green
laser beam dot can be seen at much greater distances than with a
red laser pointer.

Since green direct injection laser diodes aren't readily
available, this pointer is based on the use of Diode Pumped Solid
State Frequency Doubled (DPSSFD) laser technology. A high power IR
laser diode at 808 nm pumps a tiny block of Nd:YVO4 generating
light at 1,064 nm which feeds a KTP intracavity frequency doubler
crystal to produce the green beam at 532 nm.

Features of this unit include:

Very bright green laser at 532 nm wavelength

Output power of <5mW (Class IIIa Laser Product)

1.1 mm beam diameter at source

Momentary push button switch located on the tail, like a retractable pen

Solid, heavy duty construction

Constant wave output (as opposed to pulse output)

Takes 2 "AAA" batteries (not included)

Can be used for skypointing, projection on low clouds,
signaling, highlighting potential explosives

Dimensions: 5.6" x .5" dia

90-day warranty

Note: The on/off button is on the END of the device, not on the side like you'd expect
